The film takes place in the 1840s, yet the guns are mostly repeaters which were not in use yet (though a few might have existed). All pistols are clearly revolvers, rifles are repeaters. Yet the Mexican encampment has a storehouse with kegs of powder, and during the shootout there, several people die trying to bring back a keg of black powder as they were running out of ammo, which would have been useless as they needed bullets not powder.
The version shown in Great Britain was modified to satisfy the censors. Scenes showing horses falling, the depiction of J. Carrol Naish being shot to death after the fighting scene, and references to cutting off Chinese men's ears, were all eliminated. These scenes are in the Turner library version shown on Turner Classic Movies.
